This course stresses practical application of well test theory to design and interpret pressure transient tests. An integrated approach to well test interpretation is emphasized throughout the course. Class exercises involving hand calculations and simple spreadsheet applications will reinforce the concepts illustrated by both synthetic data sets and real field examples. Participants will be able to apply the knowledge and skills they gain in this course to their job assignments upon course completion. One personal computer is provided, at additional cost, for each two participants.

This course covers material for both conventional and unconventional reservoirs.

"It's an amazing course. The concepts, practicality, and field implementation are a perfect blend of WTA." - Senior Reservoir Engineer, Malaysia

"The number of exercises between lessons strengthened my understanding on the subject. " - Operation Petrophysicist, Malaysia
Engineers and geoscientists who want to understand well testing principles and interpretation techniques to design, analyze, report, evaluate results or intelligently participate in the well testing process. Previous experience in production and/or reservoir engineering is recommended. Previous experience in well testing is helpful but is not required.
